A text-to-speech converter is an application that is used to convert the text content entered by the user into speech with a click of a button. A text-to-speech converter should have a text area at the top so that the user can enter a long text to be converted into speech, followed by a button that converts the entered text into speech and plays the sound on click to it.
Here, we will build a fully responsive text-to-speech converter using HTML, CSS, and JavaScript.

Step-by-Step guide to build a Text to Speech Convertor
- Create a folder with the project name and create the required HTML, CSS, and JavaScript files as shown in the project structure.
- Now, use the HTML tags like textarea, button, div, head, body etc. to define the structure of the website.
- Add the styles to the HTML tags used to define the structure by selecting them with the help of given IDs and Classes.
- Utilise the speechSynthesis API of the global window object and the SpeechSynthesisUtterance to create a utteraance of the entered text.
- Next, use the speak() method of the speechSynthesis API to speak or play the created utterance as a speech.
- Handle the errors efficiently if user have not provided any text to convert.
